Researching Differentiated Accountability

I just want everyone to know that I am researching whether or not Pennsylvania will be applying for Director Spellings pilot program of Differentiated Accountability. Basically, Differentiated Accountability will allow schools who do not make their AYP numbers to show why they are not making the numbers and follow up with interventions that are appropriate to the reasons. This makes sense in theory as some schools have a large proportion of their student population identified as needing improvement and others are not making AYP goals because of a small subgroup of students that may be having trouble reaching the targeted goal. In each of these cases, the changes that would need to be made would be quite different As far as I have read, only 10 states will be accepted into the program. Two calls to the Pa Dept of Education have not been returned...
